摘要/Abstract

摘要： A global analysis of all available and identified spectra of the PO₂ radical has been performed. In this analysis, the infrared spectra of the ν₃ band, the microwave and far infrared laser magnetic resonance transitions in the ground state are fitted simultaneously to the effective Hamiltonian for asymmetric top molecules. Since the analysis absorbs reliable experimental data extensively, it bears the most precise and most complete set of molecular constants for PO₂. These molecular constants can be used to reproduce the spectra of PO₂ accurately. Attention is also paid to the similarity and difference between PO₂ and NO₂.

Abstract: A global analysis of all available and identified spectra of the PO₂ radical has been performed. In this analysis, the infrared spectra of the $\nu$₃ band, the microwave and far infrared laser magnetic resonance transitions in the ground state are fitted simultaneously to the effective Hamiltonian for asymmetric top molecules. Since the analysis absorbs reliable experimental data extensively, it bears the most precise and most complete set of molecular constants for PO₂. These molecular constants can be used to reproduce the spectra of PO₂ accurately. Attention is also paid to the similarity and difference between PO₂ and NO₂.

Key words: PO₂, global analysis, molecular constants
